Buying a Home When Much of Your Wealth Is Company Stock

Buying a home with equity-comp wealth means planning the down payment's tax cost, how lenders treat RSU income, and 2026 loan and deduction limits.

1 / 7

The short answer

For people paid largely in stock, a home purchase is mostly a question of where the down payment comes from and what selling shares will cost in tax.
Lenders size the loan from documented, repeatable income, which may count less of your RSU or bonus pay than you expect.
Budget for the full cost of ownership, including property tax, insurance, maintenance, and transaction costs, not just the monthly mortgage.
Decide the purchase range before shopping, so the house fits the plan rather than the plan bending around the house.

How can company stock fund a down payment?

Selling vested shares turns stock into cash, but any gain is taxed, and shares held one year or less are taxed at ordinary income rates.
Planning sales across tax years, trading windows, and upcoming vests can help reduce the tax drag on the amount you need.
Borrowing against a stock portfolio avoids an immediate sale, but a drop in the shares can trigger a margin call at a bad moment.
Using concentrated stock for a down payment is also a chance to reduce single-company exposure, which many people weigh alongside taxes.

How do lenders look at RSU and bonus income?

Fannie Mae recommends a two-year history of bonus, commission, or overtime income, and allows as little as 12 months with offsetting positive factors.
Some lenders count RSU income using past vests and a remaining vesting schedule; others exclude it, so policies vary widely.
Fannie Mae caps total debt-to-income at 36% for manually underwritten loans, or 45% with qualifying credit and reserves, and 50% for loans run through its automated system.
Recent job changes, pre-IPO stock, or large pending vests can complicate approval, so talk to a lender early.

Which loan types come up most?

For 2026, the baseline conforming loan limit for one-unit homes is $832,750, and the high-cost-area ceiling is $1,249,125, which applies in San Francisco.
Loans above the local limit are jumbo loans, which often require larger down payments, more cash reserves, and fuller documentation.
A fixed-rate loan keeps the payment steady; an adjustable-rate loan starts with a fixed period and then resets with market rates.
An adjustable-rate loan can make sense when you expect to move or refinance before the reset, but the payment may rise if you stay.

What tax rules apply to homeowners in 2026?

Mortgage interest is deductible on up to $750,000 of acquisition debt for loans after December 15, 2017, a limit the 2025 law made permanent.
The 2026 cap on state and local tax deductions is $40,400, but it phases down toward $10,000 once modified AGI exceeds $505,000.
These deductions only help if your total itemized deductions exceed the 2026 standard deduction of $32,200 for married couples filing jointly.
When you sell a main home owned and lived in two of the last five years, up to $250,000 of gain ($500,000 jointly) can be excluded.

Costs people tend to underestimate

Closing costs, lender fees, inspections, and in some cities a transfer tax can add a meaningful percentage to the purchase price.
In California, Proposition 13 bases property tax on purchase price, starting around 1% plus local assessments that vary by city.
Standard homeowners policies exclude earthquake and flood damage, which require separate coverage in areas where those risks apply.
Ongoing maintenance, repairs, and HOA dues belong in the monthly budget alongside principal and interest.

Key takeaways

Work backward from the down payment source, the taxes on selling shares, and how a lender will count your income.
2026 loan limits, the $750,000 interest cap, and the $40,400 SALT cap all shape the real after-tax cost.
Keep an emergency reserve after closing, because equity compensation can fluctuate in value and timing.
Confirm tax details with a CPA and loan terms with lenders; this is general education, not advice for your situation.
